Figure 1.
Analysis of myonuclei on single fibers. The number of myonuclei (N) in 106 μm3 fiber volume, (A), increased on POST-Hypoxia samples. The Nuclear Domain (ND), the fiber volume 103 micron3 containing the nuclei, (B), decreased at POST-Hypoxia samples. In (C) has been reported the myonuclear density counted in single fiber of each subject. The data are expressed as means and standard errors. Empty bars represent PRE-Hypoxia while dark bars POST-Hypoxia samples. *p ≤ 0.05.
